    Abstract: The present invention relates to the field of flash tubes for photographic use, in particular to a flash tube adapted to provide a light output adapted to FP-sync, Flat Peak. The flash tube comprises a length of glass tubing 42 enclosing a gas 43 for use in the flash tube 41, a cathode 44 inside a first end part 46 of glass tubing 42 and an anode 44 inside a second end part 47 of glass tubing 42. The cathode 44 comprises an element 50 that helps to ionize the gas 43 that is wound around the cathode 44, such that a spark stream starts from the upper part 48 of the cathode 44 and is prevented from spreading down wards on the cathode 44 and changing the arc length during the light output adapted to FP-sync.
